A famous quote from The Threepenny Opera by Bertold Brecht comes into my mind when I read what you can build with Ethereum.

What’s breaking into a bank compared to founding one?

So we are talking about blockchains, bitcoins, making money, decentralisation, Switzerland, smart contracts, clouds, trust and building central banks. I’m not sure whether it’s another kind of bullshit bingo or something to take serious.

But I like the idea of building a central bank with a decentralised tool.

In the case of the iron blogger project it could be useful to sign a contract to blog once a week. Ethereum is a currency and a possibility to create such contracts. They are called smart contracts.

First step seems to be the download of an the Ethereum wallet

After the installation it’s looking for peers and downloads the blockchain (which takes time …. > 4GB).
